AI Technical Summary

Technical Problem

Existing water bottles lack a detachable accessory connection mechanism that is visually unobtrusive, does not compromise leak-proof integrity, and does not require additional height, while allowing easy attachment and detachment of accessories like carrying loops or retaining rings.

Method used

A closure unit with a docking area featuring a recess and an elastic membrane that covers the recess, allowing a coupling element to be inserted and detached through a rotational movement, ensuring the recess remains closed and secured by frictional forces without additional height or openings.

Benefits of technology

Provides a visually seamless and leak-proof attachment mechanism for accessories, enabling easy and secure attachment and detachment without additional height or compromising leak-proof integrity.

Abstract

Closure unit (100) for connection with a drinking bottle (200'), with at least one pouring element surrounding at least one closable pouring opening, and with a lid (30') which covers the pouring opening when closed, characterized in that: - that the lid (30') has a docking area (80') for attaching an accessory (60') in which a lid wall is perforated with at least one recess (81') into which a coupling element (61') of the accessory (60') can be inserted, which can be positively connected to the lid (30') by a rotational movement; and - that an elastic membrane (70') is arranged below the recess (81') which covers the recess (81'), wherein the membrane (70') deflects by elastic deformation when the coupling element (61') is inserted into the recess (81') and, after the rotational movement has been carried out, rests against the coupled coupling element (61').
